My GNex will not vibrate at all. Haptic feedback, vibrating while ringing, and vibrating while receiving texts all will not work. I wasn't sure if I should put this in all things root but since I am rooted and romed I decided to. I'm on Liquid 1.2 and imoseyons latest exp. I'm planning to exchange it at verizon but was wondering if anyone had any ideas for fixes before that.
